In less than three months of service, German shepherd Luke sniffed out a total of €745,000 ($847,070) while patrolling the Dusseldorf airport in western Germany, German customs agents said in a statement.
The canine was recruited in February 2018, at two years of age, and then entered a lengthy program teaching him to track down large amounts of cash based on the bills' scent. He graduated in December and made 12 successful busts before the end of February.
"Luke is a valuable helper in controlling cash smuggling," customs spokesman Michael Walk said. "Considering his successful debut, we are excited to what his rate of success will be in the future."
However, Luke's nose sometimes works a bit too well — several times he discovered wads of money under €10,000 in value.
He is trained to sniff out euros, dollars, and pounds.
Luke and other sniffer dogs are a part of German authorities' effort to curb illegal money transfers involving actors like drug traffickers or terror networks.
